“After a terrible experience with another company that misdiagnosed my one-year-old Minisplit compressor as having 'toasted' electronic boards (with a $2,000 parts + labor quote and a refusal to install my warranty-covered replacements), I was incredibly frustrated. They even suggested I replace the entire system for $12,000!
Finding a company willing to work on a Minisplit and install my own parts proved challenging. After 5 or 6 rejections, "One Hour Heating & Air Conditioning of Ellis County" was a breath of fresh air. They immediately agreed to help and sent a team the next day.
The technicians quickly identified and fixed a problem with the electric line feeding the unit. Once power was restored, my supposedly broken compressor worked perfectly!
I also had a great experience with Kortling and Brian.
Highly recommend.”

“The care and service provided by Jordan was exceptional. He was pleasant,
friendly, as well as helpful. My questions were answered, and the AC was inspected and thoroughly cleaned. He showed me pictures and the unit looks brand new!! While he was here, he even fixed my water hose which was badly leaking. I recommend this company to anyone who is looking for professional and reliable service. Ask for Brittany or Jordan to be sure you have the correct office/location. You WILL NOT be sorry.”

“Excellent prompt service. CJ diagnosed the issue with out 10 year old AC unit, and guided us in the best course of action. We chose to replace the unit, and Dave and Uriel arrive the next day and expertly installed our new unit. The entire transaction was top notch, thank you for the professional service”

“Alex Prince was an amazing technician! From the moment he arrived, he was professional, respectful, and clearly knowledgeable. He took the time to thoroughly inspect my AC unit and walked me through exactly what was wrong, explaining everything in a way that was easy to understand.
What really stood out was how patient and honest he was—he didn’t rush through anything and made sure I felt confident about the next steps. It’s rare to come across someone who genuinely cares about the customer experience, and Alex definitely does. I highly recommend him to anyone needing HVAC service!”

“I recently had the pleasure of working with both Nick and Justin from One Hour Heating & Air Conditioning of Atlanta, and I couldn’t be more impressed with the service I received. Each technician came on different days and handled their responsibilities with the utmost professionalism and expertise.
Nick was incredibly thorough during his inspection, clearly explaining what was going on with my HVAC system and ultimately handling the installation of a new air unit with care, efficiency, and precision. He made a potentially stressful situation feel seamless and manageable.
Justin was just as impressive—prompt, courteous, and focused. He quickly diagnosed the issue he was assigned to address and walked me through every step with patience and clarity. His attention to detail and customer-first approach truly stood out.
Both technicians represented the company in the best way possible. Their knowledge, professionalism, and genuine dedication to quality service left a lasting impression. I highly recommend One Hour Heating & Air Conditioning of Atlanta—and if you’re lucky enough to get Nick or Justin, you’re in excellent hands!”

“Not only were we able to be seen the same day we called to have our AC inspected, we were able to get our new unit and other services completed/installed the next day!
They were able to get everything done sooner than the original timeframe they gave us and walked us through any issues they encountered with to make sure we understood what happened and how they were going to fix it.
We cannot thank Ricky, Chris, Collin and the other guys for all the help and service!”
